Bridge Withdrawal Delay Notifier-and-Claimer

WHAT IT DOES

The Bridge Withdrawal Delay Notifier & Claimer enables comprehensive monitoring and claiming of delayed bridge withdrawals. It reads bridge contract state including pending withdrawal counts, delay periods, claim windows, bridge fees, relayer status, and individual withdrawal details such as amount, recipient, timestamp, and claim status. The tool calculates time remaining before each withdrawal becomes claimable, displays ready-to-claim withdrawals prominently, and supports multiple claim methods (claimWithdrawal, executeWithdrawal, claim, withdraw) with optional custom data. Users can monitor pending withdrawals for any address, receive visual notifications of claimable status, and execute claims with a single click.

HOW TO USE

Connect your Web3 wallet and paste the bridge contract address you're interacting with. The tool never hardcodes addresses—you specify the contract you're vouching for. Enter the user address (defaults to connected wallet) and optionally a specific withdrawal nonce to target. Click "Check pending withdrawals" to fetch all pending withdrawals for the address, including amount, recipient, timestamp, delay status, and time remaining until claimable. The tool displays pending withdrawals with visual indicators showing which are ready to claim (green) and which are still within the delay period (yellow). Select the claim method (claimWithdrawal, executeWithdrawal, claim, or withdraw) and optionally provide custom claim data. Click "Claim withdrawal" to submit the transaction. The tool automatically claims the first ready withdrawal if no specific nonce is provided. Transaction status, gas costs, and confirmation are displayed upon completion.

MECHANICAL ADVANTAGE: AUTOMATED DELAY CALCULATION WITH PARALLEL STATE FETCHING

Unlike hardcoded bridge claimers that require manual delay tracking, this tool automatically fetches delay period from the contract and calculates claim eligibility for each pending withdrawal by comparing the withdrawal timestamp against the current block time. It fetches eight different state variables in parallel using Promise.all with individual error boundaries, ensuring that a revert in one view function doesn't prevent retrieval of other critical metrics. The tool intelligently fetches the first 20 pending withdrawals for an address, parsing each into a structured object with formatted amount, recipient address, timestamp, and a ready flag. It supports multiple claim method signatures and automatically selects the appropriate one based on user input. Gas estimation factors in bridge fees and claim complexity, and the tool uses receipt.effectiveGasPrice post-transaction for accurate cost reporting rather than relying on the pre-EIP-1559 gasPrice cap. Real-time time-remaining formatting provides immediate visibility into when withdrawals will become claimable.

WHAT IT CANNOT SEE

This tool cannot verify that the bridge contract is legitimate or has not been compromised. It cannot detect if the bridge oracle or relayer has been manipulated or if the contract has been upgraded or modified. Claiming may not execute at optimal gas price due to network conditions or succeed if the bridge is paused or frozen. The tool cannot recover funds if execution fails due to contract bugs or insufficient approval. It cannot verify that withdrawal parameters are valid, predict gas prices during congestion, or detect if the bridge message has been delayed or front-run. The tool cannot ensure that cross-chain state sync is accurate beyond what the bridge reports, verify off-chain bridge infrastructure security, provide financial or investment advice, guarantee claim finality, or protect against bridge exploits. It cannot notify users of pending withdrawals outside of the tool—you must actively check the tool to see pending withdrawals. The tool only fetches the first 20 pending withdrawals; large batches may not be fully displayed.

PLEASE NOTE

This tool operates on EVM-compatible chains only. It reads from and writes to bridge contracts but provides no financial or investment advice. All claim decisions remain your responsibility. Always verify contract addresses and withdrawal details before submitting transactions. The tool displays current state but does not automatically claim—you must review and confirm each transaction through your wallet. Gas costs vary by network conditions; the tool estimates but cannot guarantee optimal pricing. Withdrawal delays are enforced by the bridge contract; the tool cannot bypass or accelerate delay periods. If a withdrawal has a delay period, ensure you wait the full duration before attempting to claim.
